측두골을 침범한 다발성 골수종 1예

Multiple myeloma (MM) is a systemic manifestation of plasma cell tumor. MM is a relatively well known disease, but the involvement of temporal bone is very rare. In 1979, Lavin first reported the involvement of temporal bone in MM. Symptoms of MM with involvement of temporal bone include hearing loss, tinnitus, dizziness, facial paralysis, and otalgia. The diagnosis of MM may be considered in the presence of a temporal bone mass. Recently, we experienced a case with tinnitus, hearing impairment, and temporal bone mass. The case was later confirmed to be a MM after a pathologic review and a systemic evaluation. We report this rare case with literature reviews. (J Clinical Otolaryngol 2004;15:299-302)
